What Do Contrast Threshold Equivalent Noise Studies Actually Measure? Noise vs. Nonlinearity in Different Masking Paradigms

Alex S. Baldwin, Daniel H. Baker, Robert F. Hess, Zhong-Lin Lu
2016 PLoS ONE  
The internal noise present in a linear system can be quantified by the equivalent noise method.  ...  By applying this simple "linear amplifier" model to the human visual system, one can entirely explain an observer's detection performance by a combination of the internal noise variance and their efficiency  ...  Acknowledgments This work was funded by an NSERC grant (#46528-11) and a CIHR grant (#MT 108-18) awarded to RFH, with additional funding from the Wellcome Trust (#105624) through the Centre for Chronic  ...

Effects of forward masking on sound localization in cats: basic findings with broadband maskers

Yan Gai, Janet L. Ruhland, Tom C. T. Yin
2013 Journal of Neurophysiology  
Our findings suggest that different localization mechanisms can operate independently in a complex listening environment.  ...  Forward masking is traditionally measured with a detection task in which the addition of a preceding masking sound results in an increased signal-detection threshold.  ...  Yan for helping with computer programming and A.
